The prime minister of Tibet's government-in-exile has launched a fresh campaign for autonomy within the Chinese region of Tibet.

Lobsang Sangay says he and other senior exiled leaders want to counter the Chinese government's "misinformation" about their policy, known as the "Middle Way".

The policy calls for genuine autonomy for Tibet but not independence from China.

Mr Sangay says the new campaign aims to persuade the international community to support the Tibetan cause.

"There is total repression and total discrimination" in Tibet, he told reporters at his government's headquarters in Dharamshala, northern India.

"All this repression is making Tibetans more resentful of the Chinese government's policies and towards the Chinese government and various forms of protests are taking place."

US president Barack Obama and other Western leaders have called on Beijing to resume talks with the Dalai Lama's envoys on autonomy that broke down in 2010 after making no headway.

Beijing has ruled Tibet since 1951, a year after invading.

It has already dismissed the renewed push for the "Middle Way" approach, which would include handing Tibetans decision-making positions in the region.

The launch comes after the Dalai Lama, who remains the spiritual leader of Tibetans, called for democracy in China and offered prayers for Tiananmen Square victims on the 25th anniversary of the crackdown.

Moscow's words and actions — including the alleged poisoning of a former spy — are not the results of random aggression but rather fall into distinct patterns that can help us anticipate Russia's next moves under Vladimir Putin.
